ELECTRIC SIGN.

Application filed October 7, 1922. Serial No. 592,958.

This invention relates to improvements in electric signs and'has for itsobject the pro vision of a novel, simple and economical electric sign.

i 5 1n the drawing, A represents the terminals for the electriccurrent.-B is a wire of ClIIOIYIGl or other resistant metallic electrirent ispassed.

L'To increase or improve the quality of the light, the wire B may becoated-with some oxide such as magnesium oxide of powerful photogenet-icproperties.

2.5 I have illustrated herein a sign showing only three letters of thealphabet but it is obvious that a letter of any form can be made bydoubling or curvin the wire as shown in the letters A and and by the 80use of divisions G which are shaped to conform to the shape of theparticular letters used in the sign." The wire B can be made of anyresistant metal which does not oxidize or melt and which is luminiferouswhen a current is passed thcrethrough. Apropcr metal for the purpose inan alloy of nickel and chromium known as chromel metal.

l-laving thus described my invention, what I claim is:- i 40 1. Anelectric sign having the individual letters formed ofn continuous singlestrand of non-oxidizable resistance metal exposed to the air, theindividual letters being separated by thick portions of non-luminousmetal forming a part of the electric circuit so that the individualletters are illumined and the metallic connectors joining said lettersare unilhnnincd, all of the letters of said sign being in a singleplane.

2. An electric sign having letters formed of acontinuous single strandof non-oxidizable resistance metal exposed to the air, no part of saidstrand contacting with any other part in said sign, the individualletters he ing separated by non-1uminousmetal formingpart of theelectric circuit, all of said letters being in a single plane.

In testimony whereof I hereunto aflix my signature.

HUGO MOCK.
